jquery - Backbone Model Save with Specific Attributes, How to Post some attrs when syncing? -

-

i've got new model tons of attributes. when #saveing expect backbone #post because id null, works correctly.

$ = require('jquery') - = require('underscore')  model = new backbone.model({   id: null,   name: "tom",   cat: false,   dog: true,   //... many more attrs   whiskers: false,   tail: true });

now want send small subset of attributes server on post.

with jquery can write this:

data = _.pick(model.attributes, 'name', 'dog', 'tail'); $.post(model.url(), data);

how can backbone?

i did sync below, felt wrong.

data = {} data.attrs = _.pick(model.attributes, 'name', 'dog', 'tail'); model.sync('create', model, data)

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
